Keep testing positive for meth and haven't done it

Was told metformin can have you test positive for meth

Interested in more discussions like this? Go to the Addiction & Recovery Support Group.

I keep testing positive for meth but my previous probation officer & now my parole officer do not care to take into consideration my medications (Adderall & Trazodone) & if I’ve taken Sudafed. They never say anything about amphetamines only methamphetamines that come back & say my medications only come back as amphetamines even though I show proof from credited medical schools/hospitals that’s proven it & can’t determine the illicit to synthetic. How can I prove it anymore?

Is that based on a quick dip test or are you going to or are they sending to an actual lab? It's not real uncommon to get a false positive on a dip if you are on Adderall. It should be going to a lab for sure. They can determine and rule out the meth OR confirm if it's really there. If it tests positive there...well, I don't know what to tell you.
BTW, I am a Licensed drug counselor.

Hi there, I'm from South Australia. I take Metformin for my Diabetes2 and recently tested positive for Methamphetamine when pulled over by police. I did not take any drugs except my Metformin.
I've had an independent test at a certified testing place and the result is the same. My Lawyer wants more information.
Is it possible for someone there at Mayo Clinic to reply to me stating that Metformin can give a false positive result for methanphetamine. Many thanks.

You must be frustrated, but unfortunately Mayo Connect is a community of patients and Mayo's moderators and can not provide direct medical or legal advice.

Have you contacted the provider who prescribed Metformin or a pharmacist and asked if it could be causing the false positive.

Thank you for your reply. Yes I have and no they won't write a support letter because they have read about it, but haven't actually dealt with this matter direct.

I did a Google search first. Mayo have a site that says Metformin and other prescribed drugs can give a false positive result. Then I contacted your support group

If you have been doing Google searches, you may have read some of them.

You might try searching PubMed for published medical articles on subject.
https://pubmed.ncbi.nlm.nih.gov/
Example, here is one, but it is very old (2015):
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6170116/
Also, found this from Univ of Michigan about different types of tests and what interferes testing:

What type of documentation do you require?

The pharmacist is the person to talk to regarding this issue.

Thank you for your reply and the helpful information. My Lawyer says he wants a support letter from the prescribing doctor or pharmacist whom I get my Metformin from. But they won't due to some privacy problem. So that's why I've come to you. I think my Lawyer basically wants someone who knows about this situation to just say that they know Metformin can give false positives. He won't accept the webpages, not even the one from Pubmed. It is frustrating.
